Major New Features

ONVIF Profile-S support on TCIV

TCIV now fully supports and is compliant with the ONVIF Profile-S specification. As an industry standard, Profile-S can be used to integrate with a variety of VMS and NVR products. Both video and audio 1-way streaming is available.

Dual-stream functionality on TCIV

TCIV now supports dual-streaming functionality, with which two independent video streams can be separately initiated and controlled. Streams can be configured with different protocols (SIP, RTSP, ONVIF, HTTP), different codecs and resolutions, and are both lip-synced if audio and video are being used, using the industry-standard RTCP protocol.

RTSP support for TCIV video stream

RTSP is an industry-standard network control protocol for establishing and controlling media streams. TCIV now comes with full support for RTSP video streams.

RTSP audio stream support for all Turbine devices

RTSP is an industry-standard network control protocol for establishing and controlling media streams. All Turbine intercom devices and kits now fully support RTSP for outgoing audio streams.

RTSP support for TCIV H.264 stream for AlphaCom systems

Added RTSP H.264 support on ITSV-1 to initiate video stream from TCIV in AlphaCom mode.

ITSV-1 new features and improvements

ITSV-1 has an Integrated Video preview function with TCIV and other third-party IP cameras (SIP, Pulse and AlphaCom). We have increased the number of available RTSP or HTTP MJPEG stream clients to 100. We shortened the registration interval to align it with our Pulse system. In line with our Cybersecurity strategy, constraint mode is now enabled by default, so some more advanced configuration options and tools are put behind password protection.

Image quality improvements for TCIV

Low-level optimizations were made for the AEWB engine (Automatic Exposure and White Balancing), resulting in the following image-quality improvements: better low-light performance, better overall color accuracy and contrast, and smoother, dynamic dark-light transitions.

Lip-sync of Audio and Video on TCIV

Audio and Video streams initiated using ONVIF or RTSP protocols are lip-synced for both streaming and recording, implemented using the industry-standard RTP Control Protocol (RTCP).

Keep-alive for improved VoIP NAT traversal (*)

NAT keep-alive is a feature that sends very tiny UDP data packets from a VoIP client to the router to show that the port is still in use. Turbine are now sending keep-alives every 25 seconds.

IP Station support for RFC3891 SIP “Replaces” Header (*)

IP Stations now support Reinvite / INVITE with replaces, which is a quite common function used in SIP environments. The needed function is described in RFC3891.

IP Multicast audio support for Pulse Intercom (*)

IP intercom stations now support IP multicast audio when configured in Pulse mode. Previously, only SIP mode was supported. Up to 10 multicast IP addresses can be configured.

Chinese font on Turbine OLED display

Turbine now supports Chinese language characters with a new font package. Our new vsf- chinese-font_x.x.x.x_armel.ipk package can be installed on Turbine stations. (You can find the download on AlphaWiki.)

TCIV-5, TKIE-3 and IP-LCM firmware support

Turbine firmware now supports our new TCIV-5, TKIE-3 and IP-LCM models.

Advanced GPO configuration for Pulse and SIP

Turbine now has the option to use standard Relay configuration or to use the new, more advanced GPO (output) configuration.

New DAK call actions

These new call actions have been added under DAK settings: Hold Call and Defer Call.

VS-IMT new functions and improvements

We have added support for new Video, RTSP and ONVIF settings, syslog configuration, new DAK call actions and other smaller improvements.

Only a limited set of new functions are available for INCA intercoms. New INCA functions from table above are items with an asterix (*)
